Abstract:
In order to discover novel environmental friendly insecticide,sixteen novel 2-(brominated furanyl or thiophenyl)-1,3-dithiane derivatives were synthesized via condensation of brominated furaldehyde or thiophenecarboxaldehyde and 2-substituted-1,3-propanedithiol,and their structures were confirmed with 1H NMR,elemental analysis or mass spectrum.The preliminary bioassay showed that all novel compounds have certain insecticidal activity at 600 μg/mL,and the lethality of compound M11 against Myzus persicae reaches 90%.
